A)what special properties of ALCL3 and BF3 makes them Bronsted acids?
B) Which of the following is the most acidic?
A) CH3OH
B)CH3OH2+
c)CH3NH2
D)CH3NH3+
E)CH3CO2H
A) Both AlCl3 and BF3 are not Bronsted acids. The definition of Bronsted acid is any substance that donates proton is callled as Bronsted acid. However, these are Lewis acid which states that any substance which can accept lone pairs of electrons are called as Lewis acids. As, both AlCl3 and BF3 both accepts lone pairs of electrons these are Lewis acids and not Bronsted acids
B) The stonger acid will be B) CH3OH2+, as it will form a nuetrla molecule (more stable conjugate base) CH3OH after loosing proton.
